Description
The present invention relates to the muriatic production method of aluminium.Particularly produce the method for polymerize aluminum chloride.
For satisfying the demand of tap water and Industrial Wastewater Treatment, the several years, the production method of high-efficient water purification agent polyaluminium chloride has been carried out more research.Disclosed patent application CN 87103009, CN85102295, CN85107358 all belong to the research of this respect.Produce the process of polymerize aluminum chloride with bauxite, comprise three main operations, activate promptly that calcination, mineral acid are molten soaks, modulates (or pyrolysis) polymerization.Traditional technology with production polymerize aluminum chlorides such as aluminum chloride, aluminium hydroxide, aluminium ash, aluminium foils has been reformed in these researchs.Opened up new road for directly using bauxite, coal gangue to produce polymerize aluminum chloride.But disclosed research still has the deficiency of four aspects: 1, the ingredient requirement of Shi Yonging contains Al
2O
3High (25～80%), the activation calcination temperature is higher, the dust rate height; 2, the chemical materials that needs in the technological process is wide in variety, CN87103009, CN85102295 have adopted hydrochloric acid, sulfuric acid mixing acid, residual in the product have impurity such as unnecessary sulfate radical, calcium chloride, uses the hydrochloric acid of higher concentration, increased the volatilization loss of hydrochloric acid and the difficulty of labour protection; 3, long flow path, especially CN85102295 have increased sulfuric acid baking again after bauxite activation calcination, multistage is molten to be soaked, and make flow process seem very tired and lock; 4, higher polymerization temperature has all been adopted in disclosed research, causes the pressure-bearing to equipment, and requirement for anticorrosion is also high.
The purpose of this invention is to provide and a kind ofly utilize that kaolin, dilute hydrochloric acid normal pressure moltenly soak, the method for normal temperature liquid polymerization explained hereafter polymerize aluminum chloride.This method can be simplified the existing processes process, improves the technology control condition.Make existing utilize the technical process of bauxite, bastard coal masonry raw material more to become perfect, reasonable, adaptability is stronger.
Solution of the present invention is with after the kaolin moulding, carries out the level bed static activating under 500 ± 50 ℃ temperature condition, thereby has avoided high dust rate and huge dust collecting system.Activated material is crushed to 180～240 orders and makes the molten raw material that soaks of hydrochloric acid.Hydrochloric acid is molten when soaking, concentration of hydrochloric acid is 8～10%, temperature is a little more than 100 ℃, the pH value of control reaction end is more than 2.8, and this moment, the basicity of leach liquor was 18～20%, and leach liquor is at 55～80 ℃ of hydrolytic polymerizations, and with the adding of aluminate do initiation synergist, when the pH value of polymer fluid rises to 3.7 when above, the cooling slaking contains Al in liquid product
2O
3Reach 10～11%, basicity reaches 80% when above, dehydrates the output solid phase prod again.
Accompanying drawing is the technological process skeleton diagram
The present invention because in having adopted, low temperature level bed static activating kaolin, low-concentration hcl is molten to be soaked, aluminate do to cause synergist, has not only avoided high-temperature operation, and has reduced dust rate, is conducive to reduce equipment investment, is conducive to labour protection. Simplify flow process, improved process control condition. Make whole flow process more perfect, reasonable. Solution of the present invention also is applicable to and contains Al2O
3Be recovered according to a price all kinds of bauxite, the gangue of grade.
Enforcement of the present invention is to contain Al
